North Korea is one secretive country, but it’s first major failure under the reign of Kim Jong-un was widely observed by the United States, South Korea, and Japan: a rocket exploded a mere 80 seconds after being launched.

We already know that things are pretty strict in North Korea, but even with the passing of “Dear Leader,” it looks like the rules are getting even stricter. In fact, if you are caught using a cell phone, you will be a deemed a war criminal and dealt with accordingly.

North Korea is working on a GPS jamming device that would work with an effective range of over 100 kilometres. Yes, this would be very frustrating for any foreigners who are trying to make their way around Pyongyang, but it’s not like North Korea is terribly open to random tourists either. This clearly has more of a military application, disrupting GPS signals to the point of making them utterly unusable.

Anyone planning on illegally crossing the North/South Korean border better think twice, the government has deployed a couple sentry robots that can sense heat and motion and deploy 40mm grenades at the target, or just fire off a couple thousand rounds of ammunition its way. Audio and video is sent back to the command center allowing them to make the call on whether or not the response requires such offensive action. Check the video below for a peak at the command UI.
